The plunge cut is made with the guide
bar nose. Begin the plunge cut by
applying the lower portion of the guide
bar nose to the tree at an angle. Cut until
the depth of the kerf is about the same
as the width of the guide bar. Next, align
the saw in the direction in which the
recess is to be cut.
With the saw at full throttle, insert the
guide bar in the trunk.
Avoid repositioning the saw more than

engaged in the kerf to keep the felling
cut straight. If the saw begins to pinch,
insert a wedge to open the cut. On the

Felling a tree that has a diameter
greater than the length of the guide bar

methods are extremely dangerous
because they involve the use of the
nose of the guide bar and can result in
kickback. Only properly trained profes-

First, cut a large, wide felling notch.
Make a plunge cut in the center of the
notch.
Warning!
Sectioning Method
There is an extreme danger of kick-
back at this point. Extra caution must
be taken to maintain control of the
saw. To make the felling cut, follow
the sectioning method described
previously.
For the sectioning method make the first
part of the felling cut with the guide bar
fanning in toward the hinge. Then, using
the bumper spike as a pivot, reposition
the saw for the next cut.
